Long-term safety and efficacy of canagliflozin as add-on therapy to teneligliptin in Japanese patients with type 2 diabetes.

ABSTRACT: AIM:To evaluate the long-term safety and efficacy of canagliflozin as add-on therapy in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control with teneligliptin monotherapy. METHODS:This open-label 52-week study was conducted in Japan. Patients received canagliflozin 100?mg added to teneligliptin 20?mg orally once daily for 52?weeks. The safety endpoint was the incidence of adverse events (AEs). The efficacy endpoints included changes in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG) and body weight from baseline to week 52 (with last observation carried forward). RESULTS:Overall, 153 patients entered the treatment period and 142 completed the study. The overall incidence rates of AEs and drug-related AEs were 69.9% and 22.9%, respectively. Most AEs and drug-related AEs were mild or moderate in severity. There were no previously undescribed safety signals. The mean changes in HbA1c, FPG and body weight were -0.99% (95% confidence interval [CI] -1.12 to -0.85), -38.6?mg/dL (95% CI -43.4 to -33.9) and -3.92% (95% CI -4.53 to -3.31), respectively. These effects were maintained for 52?weeks without attenuation. HbA1c and body weight were both decreased in 82.24% of patients at the end of the treatment period. Reductions in postprandial glucose were observed at weeks 24 and 52. CONCLUSIONS:No new safety risks with this combination were identified, and sustained improvements in HbA1c, FPG and body weight were observed. The findings suggest that long-term co-administration of canagliflozin with teneligliptin is well tolerated and effective in Japanese patients with T2DM who have inadequate glycaemic control on teneligliptin alone.

Project description:IntroductionTeneligliptin is a dipeptidyl peptidase 4 inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. We performed a long-term post-marketing surveillance (RUBY) to obtain real-world evidence regarding the safety and efficacy of teneligliptin in Japan.MethodsThis 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs) and laboratory variables. Data were evaluated in all patients and in patients divided according to baseline renal function across categories of estimated glomerular filtration rate (G1-G5) and dialysis. Safety was assessed as the incidence of ADRs and efficacy was assessed in terms of glycaemic control, for up to 3 years.ResultsOf 11,677 patients registered, 10,696 and 10,249 were evaluable for safety and efficacy analyses, respectively. The median duration of exposure was 1096 days. ADRs occurred in 412 patients (3.85%) and were serious in 117 patients (1.09%). The most frequent ADR class was gastrointestinal disorders (0.68%), which included constipation. There were no new ADRs warranting attention beyond those already described in teneligliptin's package insert. ADRs and serious ADRs in renal function subgroups occurred in 3.24-7.14% and 0.65-5.36% in G1-G5, and 4.49% and 1.92% in patients on dialysis, respectively. Reduction in HbA1c was sustained for 3 years after starting teneligliptin (- 0.70% ± 1.36%, p < 0.001 at 3 years). The least-squares mean changes in HbA1c adjusted for baseline were - 0.76% to - 0.66% in G1-G5 at 3 years. Glycated albumin levels decreased in patients on dialysis (- 2.92% ± 4.78% at 3 years).ConclusionThere were no new safety or efficacy concerns about teneligliptin used in long-term, real-world, clinical settings in patients with T2DM with any stages of renal impairment.Trial registrationJapan Pharmaceutical Information Center clinical trials database identifier: Japic CTI-153047.

Project description:Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ? 65 years and <65 years.Pooled adverse event data from three placebo-controlled trials of 76-206 weeks' duration in older (? 65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test).A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ? 65 years) with saxagliptin and six (none aged ? 65 years) with placebo. Older patients rarely experienced symptomatic confirmed hypoglycemia (fingerstick glucose ? 50 mg/dL; saxagliptin, n=1; placebo, n=2).Saxagliptin add-on therapy was generally well tolerated in older patients aged ? 65 years with type 2 diabetes mellitus, with a long-term safety profile similar to that of placebo.
